2308-1DCGI

Overview

The Renesas Electronics 2308-1DCGI is a 3.3V PLL zero-delay clock multiplier designed for high-speed clock distribution and multiplication applications. It operates within an input frequency range of 10 MHz to 133 MHz, providing eight LVCMOS outputs organized into two banks of four. The device achieves zero delay by aligning the phase between the incoming clock and output clocks. Key electrical specifications include a maximum operating frequency of 133 MHz, a cycle-to-cycle jitter of less than 200 ps, and an output skew of under 200 ps. It functions at a supply voltage of 3.3 V and is housed in a 16-pin SOIC package.

Feature Summary

• Zero-delay operation synchronizes output phases with the input clock reference
• Distributes one input clock to two independent banks of four outputs each
• Supports external feedback loop configuration for flexible delay control
• Features separate output enable controls for each output bank

Applications

• High-speed clock distribution networks
• System synchronization requiring low skew
• Multiplication of reference clock signals

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence or limited availability. Confirm that the specific suffix matches the required package type and temperature rating. Ensure compliance with moisture sensitivity level (MSL) handling procedures during storage and assembly to prevent damage.

Selection Notes

Select the 2308-1DCGI when a single input clock must drive multiple loads with precise phase alignment. This model provides a fixed multiplication ratio suitable for standard system requirements. Verify that the 3.3V logic levels match the receiving components. Consider the SOIC-16 footprint constraints during PCB layout design.

Part Context

This component belongs to the IDT 2308 family of clock multipliers, originally developed by Integrated Device Technology before its acquisition by Renesas Electronics. The family addresses high-speed digital systems requiring reliable clock generation. The 2308-1DCGI represents the commercial grade variant in the standard SOIC package.

Replacement Considerations

Direct replacements include other members of the 2308 series such as the 2308-2DCG or 2308B-1DCG, provided the multiplication ratios and pinouts are compatible. Cross-reference datasheets to ensure identical package dimensions and electrical characteristics before substitution.
